General (Cont'd)
Model FT heaters are design-certified by the Canadian Standards As-
sociation (CSA) to ANSI Z83.8a and CGA 2.6a for industrial/com-
mercial installations in the United States and Canada. Models FT 30,
45 and 60 are approved by the Canadian Standards Association to IAS
10-96 for residential installations in both the United States and Canada.
All heaters are available for use with either natural or propane gas.
The type of gas, the firing rate, and the electrical characteristics are on
the unit rating plate.
WARNING: Gas-fired appliances are not
designed for use in hazardous atmospheres
containing flammable vapors or combustible
dust, in atmospheres containing chlorinated or
halogenated hydrocarbons, or in applications
with airborne silicone substances. See Hazard
Levels, Page 1.
WARNING: Should overheating occur, or the gas
supply fail to shut off, shut off the manual gas
valve to the appliance before shutting off the
electrical supply.
WARNING: Do not use this appliance if any part
has been under water. Immediately call a
qualified service technician to inspect the
appliance and replace any gas control which has
been under water.
1. Installation Codes
These units must be installed in accordance with local building codes.
In the absence of local codes, in the United States, the unit must be
installed in accordance with the National Fuel Gas Code (latest edi-
tion). A Canadian installation must be in accordance with the CAN/
CGA B149.1 and B149.2 Installation Code for Gas Burning Appli-
ances and Equipment. These codes are available from CSA Informa-
tion Services, 1-800-463-6727. Local authorities having jurisdiction
should be consulted before installation is made to verify local codes
and installation procedure requirements.
Special Commercial Installations (Aircraft
Hangars/Repair Garages/Parking Garages)
Installations in aircraft hangars should be in accordance with ANSI/
NFPA No. 409 (latest edition), Standard for Aircraft Hangars; in pub-
lic garages in accordance with ANSI/NFPA No. 88A (latest edition),
Standard for Parking Structures; and for repair garages in accordance
with ANSI/NFPA No. 88B (latest edition), Standard for Repair Ga-
rages. ANSI/NFPA-88 (latest edition) specifies overhead heaters must
be installed at least eight feet above the floor. In Canada, installations
in aircraft hangars should be in accordance with the requirements of
the enforcing authorities, and in public garages in accordance with
CAN/CGA B149 codes.
ANSI/NFPA 409 (latest edition) specifies a clearance of ten feet to the
bottom of the heater from the highest surface of the top of the wing or
engine enclosure of whatever aircraft would be the highest to be housed
in the hangar, and a minimum clearance of eight feet from the floor in
other sections of aircraft hangars, such as the offices, and shops which
communicate with areas used for servicing or storage. The heaters
must be located so as to be protected from damage by aircraft or other
objects such as cranes and movable scaffolding. In addition, the heat-
ers must be located so as to be accessible for servicing, adjustment,
etc.
2. Warranty
Refer to the limited warranty information on the Warranty Card in the
"Owner's Envelope".
Warranty is void if ...
a. Wiring is not in accordance with the diagram furnished with the
heater.
b. The unit is installed without proper clearance to combustible
materials.
c. The heater is connected to a duct system or if the air delivery
system is modified.
3. Uncrating and Preparation
This unit was test operated and inspected at the factory prior to crating
and was in operating condition. If the heater has incurred any damage
in shipment, document it with the transporting agency and contact your
Reznor distributor.
Check the rating plate for the gas specifications and electrical charac-
teristics of the heater to be sure that they are compatible with the gas
and electric supplies at the installation site.
Read this booklet and become familiar with the installation require-
ments of your particular heater. If you do not have knowledge of local
requirements, check with the local gas company or any other local agen-
cies who might have requirements concerning this installation.
Before beginning, make preparations for necessary supplies, tools, and
manpower. If the installation includes optional vertical louvers or a
downturn nozzle, install these options before the heater is suspended.
Follow the instructions included in the option package; option pack-
ages are shipped separately.
4. High Altitude Operation
If the heater is being installed in an altitude above 2000 ft (610M),
check the rating plate to determine what must be done to prepare the
heater for high altitude operation.
NOTE:
A heater equipped with a two-stage valve must be factory-built
for high altitude installation.
Check the rating plate, determine which circumstance below applies,
and follow the instructions.
•
If
the altitude range on the rating plate
agrees with the altitude at
the site
, no further action is required. Proceed with the installation.
•
If
the altitude range on the rating plate
reads "Sea Level" and the
altitude at the site is between 2000 ft and 6000 ft (610M to 1830M)
and the heater has a single-stage gas valve
, install the heater and
follow the instructions in Paragraph 12 to derate by manifold gas
pressure adjustment.
•
If
the altitude range on the rating plate
reads "Sea Level" and the
altitude at the site is above 6000 ft (1830M) and the heater has a
single-stage gas valve
, in addition to adjusting the manifold pres-
sure, it will be necessary to replace the combustion air pressure switch.
Order the appropriate switch from the list below and replace the
switch before suspending the heater.
After the heater is installed, follow the instructions in Paragraph 12
to derate by adjusting the manifold gas pressure.
